Na electronic configuration is: 1sĀ² 2sĀ² 2pā¶ 3sĀ¹. In this article, we will study how electrons are arranged in different shells and subshells in the Na atom.
Sodium- Na Sodium
(Na) is a chemical element with the symbol Na and has an atomic number of 11. It is a soft, silvery-white, highly reactive metal that belongs to the alkali metal group of elements in the periodic table. Sodium is one of the sixth most abundant elements in the Earth's crust and is essential for many biological processes in living organisms. Sodium is highly reactive and can easily lose its valence electron to form a positively charged ion, Na+. Therefore, it is commonly found in ionic compounds such as sodium chloride (NaCl), which is commonly known as table salt. Sodium is also used in the production of various chemicals, including sodium hydroxide (NaOH), which is used in the manufacture of soap and paper. Sodium is also used in the production of sodium carbonate (Na2CO3), which is used in glass production, water treatment, and other industrial processes. Sodium is an important nutrient for humans and is essential for many bodily functions, including regulating blood pressure, maintaining proper fluid balance, and transmitting nerve impulses. However, excessive sodium intake can lead to health problems such as high blood pressure and cardiovascular disease. Therefore, it is important to consume sodium in moderation and to choose low-sodium food options.
1. Electronic Configuration of Na
The electronic configuration of Na (sodium) can be represented as: 1s2 2s2 2p6 3s1 This configuration indicates that sodium has 11 electrons distributed in its electron shells. The first shell has 2 electrons, the second shell has 8 electrons, and the third shell has 1 electron. The outermost shell of sodium is the third shell with 1 electron in the 3s orbital. Sodium's outermost electron is a valence electron, which participates in chemical reactions and bonding with other atoms.
2. Distribution of Electrons
In Shell in Na Atom The atomic number of sodium (Na) is 11, which means it has 11 electrons. The distribution of these electrons in the electron shells can be determined by using the following formula: 2n2 where n is the number of the shell, starting from the innermost shell. According to this formula, the maximum number of electrons that can be accommodated in the first shell is 2(12) = 2. Therefore, the first shell of the sodium atom contains 2 electrons. The second shell can hold a maximum of 2(22) = 8 electrons. Since sodium has 11 electrons, there is 1 electron remaining after the first and second shells are filled. These 11 electrons occupy the three shells. So the electron distribution in the sodium atom can be represented as follows: 2, 8,1. The electron configuration of an atom determines its chemical properties, including its reactivity and ability to form bonds with other atoms. Sodium's outermost electron is a valence electron, which is responsible for its reactivity and ability to form ionic bonds with other elements.
3. Valence Electrons
In Na Sodium (Na) has one valence electron. Valence electrons are the electrons in the outermost shell of an atom that participate in chemical bonding. In the case of sodium, the outermost shell is the third shell, which contains one electron in the 3s orbital. This valence electron is loosely bound to the nucleus of the atom and is easily lost, making sodium a highly reactive metal. Sodium readily donates this valence electron to other atoms, particularly non-metals, to form ionic compounds.
5. Valency of Na
The valency of an element is the number of electrons an atom of the element can lose or gain to form a stable compound. Sodium (Na) has one valence electron in its outermost shell, which it can lose to form a stable ion with a full valence shell. Therefore, the valency of sodium is 1. When sodium loses its valence electron, it forms a positively charged ion with a charge of +1. This sodium ion is denoted as Na+, and it is commonly found in ionic compounds such as sodium chloride (NaCl).
